+
+```java
+//you can configure the fragment by the configuration builder
+CameraFragment cameraFragment = CameraFragment.newInstance(new Configuration.Builder().build());
+
+getSupportFragmentManager().beginTransaction()
+                .replace(R.id.content, cameraFragment, FRAGMENT_TAG)
+                .commit();
+```
+
+## Actions
+
+You can directly take a photo / video with
+```java
+cameraFragment.takePhotoOrCaptureVideo();
+```
+
+[![gif](https://raw.githubusercontent.com/florent37/CameraFragment/master/media/take_photo.gif)](https://github.com/florent37/CameraFragment)
+
+Flash can be enable / disabled ( `AUTO` / `OFF` / `ON` ) with
+
+```java
+cameraFragment.toggleFlashMode();
+```
+
+[![gif](https://raw.githubusercontent.com/florent37/CameraFragment/master/media/switch_flash.gif)](https://github.com/florent37/CameraFragment)
+
+Camera Type can be modified ( `BACK` / `FRONT` ) with
+
+```java
+cameraFragment.switchCameraType();
+```
+
+[![gif](https://raw.githubusercontent.com/florent37/CameraFragment/master/media/switch_camera.gif)](https://github.com/florent37/CameraFragment)
+
+Camera action ( `PHOTO` / `VIDEO` ) can be modified with
+
+```java
+cameraFragment.switchAction();
+```
+
+[![gif](https://raw.githubusercontent.com/florent37/CameraFragment/master/media/switch_action.gif)](https://github.com/florent37/CameraFragment)
+
+And you can change the captured photo / video size with
+
+```java
+cameraFragment.openSettingDialog();
+```

+
+# Listeners
+
+## Result
+
+Get back the result of the camera record / photo in the `CameraFragmentResultListener`
+
+```java
+cameraFragment.setResultListener(new CameraFragmentResultListener() {
+       @Override
+       public void onVideoRecorded(byte[] bytes, String filePath) {
+                //called when the video record is finished and saved
+
+                startActivityForResult(PreviewActivity.newIntentVideo(MainActivity.this, filePath));
+       }
+
+       @Override
+       public void onPhotoTaken(byte[] bytes, String filePath) {
+                //called when the photo is taken and saved
+
+                startActivity(PreviewActivity.newIntentPhoto(MainActivity.this, filePath));
+       }
+});
+```
+
+## Camera Listener
+
+```java
+cameraFragment.setStateListener(new CameraFragmentStateListener() {
+
+    //when the current displayed camera is the back
+    void onCurrentCameraBack();
+    //when the current displayed camera is the front
+    void onCurrentCameraFront();
+
+    //when the flash is at mode auto
+    void onFlashAuto();
+    //when the flash is at on
+    void onFlashOn();
+    //when the flash is off
+    void onFlashOff();
+
+    //if the camera is ready to take a photo
+    void onCameraSetupForPhoto();
+    //if the camera is ready to take a video
+    void onCameraSetupForVideo();
+
+    //when the camera state is "ready to record a video"
+    void onRecordStateVideoReadyForRecord();
+    //when the camera state is "recording a video"
+    void onRecordStateVideoInProgress();
+    //when the camera state is "ready to take a photo"
+    void onRecordStatePhoto();
+
+    //after the rotation of the screen / camera
+    void shouldRotateControls(int degrees);
+
+    void onStartVideoRecord(File outputFile);
+    void onStopVideoRecord();
+});
+```
+
+## Text
+
+CameraFragment can ping you with the current record duration with `CameraFragmentTextListener`
